TNPSC – WHITTAKER’S FIVE KINGDOM CLASSIFICATION
- H. Whittaker classified organisms based on
- Cell Structure
- Thallus Organisation
- Mode of Nutrition
- Reproduction
- Phylogenetic Relationship
- Whittaker classified living organisms into
- Prokaryotic Organisms (KINGDOM = MONERA)
- Eukaryotic Organisms
- Eukaryotic organisms can be further classified into
- Unicellular Organisms (KINGDOM = PROTISTA)
- Multicellular Organisms (KINGDOM = FUNGI, PLANTAE, ANIMALIA)
